Summary:An open-channel stiffener for stiffening a panel has a bonding flange for bonding the stiffener to the panel through a bondline formed between the bonding flange and the panel to form a stiffened panel. The open-channel stiffener has a cross-sectional shape that aligns, or substantially aligns, a shear center of the stiffener with a centroid of the stiffener and aligns the shear center proximate an edge of the bondline, and removes the need for a radius filler noodle. A plurality of perforations may be formed through the bonding flange to permit an adhesive to wick into the perforations and create a mechanical interlock between the bonding flange and the panel. 本发明提供种用于加强面板的开放通道加强筋，此开放通道加强筋包括结合凸缘，此结合凸缘用于借助形成在结合凸缘与面板之间的粘结层将加强筋结合至面板以形成加筋面板。开放通道加强筋具有这样的横截面形状，此横截面形状使加强筋的剪切中心与加强筋的形心对准或基本对准并且使剪切中心近似对准粘结层的边缘，并且消除对半径填料软条的需求。可以穿过结合凸缘形成多个穿孔以允许粘合剂依靠毛细作用进入到穿孔中，以在结合凸缘与面板之间构建机械互锁。
